Research Abstract

It is suggested that minimal chronic inflammation caused by periodontal disease can become the arteriosclerotic exacerbation factor. On the other hand, it is reported by ingestion of the dark cocoa that a cardiovascular event incidence decreases, and a cardiovascular event suppressant effect of epicatechin(EC) which is the chief ingredient attracts attention. I paid my attention to Adipocyte-macrophage interaction and, in this study, examined the molecular mechanism of the cardiovascular event suppressant effect by the EC. As a result of having analyzed the change of inflammatory related molecules when I added LPS stimulation to the co-cultures, I was able to confirm the producing decrease of inflammatory related molecules by adding EC.
These results suggested the possibility that a cardiovascular event incidence decreased by anti-inflammatory effect of the EC.
